Kalanchoe plant named ‘Lican’

ABSTRACT

A new and distinct cultivar of Kalanchoe plant named ‘Lican’, characterized by its numerous, large, and intense purple-colored flowers; upright and uniform plant habit; freely branching growth habit; dark green and glossy leaves; early flowering; and excellent postproduction longevity.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe plant, botanically known as Kalanchoe blossfeldiana, and hereinafter referred to by the name ‘Lican’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program was to create new free-branching Kalanchoe cultivars with compact plant habit, numerous flowers, and attractive foliage and flower coloration.

The new Kalanchoe originated from a cross made by the Inventor in 1996 of the Kalanchoe blossfeldiana cultivar Iztac, disclosed in U.S. Plant Pat. No. 10,455, as the female, or seed, parent with the Kalanchoe blossfeldiana cultivar Isabella, disclosed in U.S. Plant Pat. No. 9,427, as the male, or pollen, parent. The cultivar Lican was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in De Lier, The Netherlands.

Asexual reproduction of the new Kalanchoe by terminal cuttings taken at De Lier, The Netherlands, since 1996 has shown that the unique features of this new Kalanchoe are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar Lican has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Lican’. These characteristics in combination distinguish ‘Lican’ as a new and distinct cultivar:

1. Numerous, large, and intense purple-colored flowers.

2. Upright and uniform plant habit.

3. Freely branching growth habit.

4. Dark green and glossy leaves.

5. Early flowering.

6. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the female parent, the cultivar Iztac. In side-by-side comparisons conducted by the Inventor in De Lier, The Netherlands, plants of the new Kalanchoe differ from plants of the cultivar Iztac in the following characteristics:

1. Plants of the new Kalanchoe are more compact than plants of the cultivar Iztac.

2. Plants of the new Kalanchoe have smaller leaves than plants of the cultivar Iztac.

3. Flowers of plants of the new Kalanchoe are intense purple in color whereas flowers of plants of the cultivar Iztac are dark pink in color.

Plants of the new Kalanchoe can be compared to plants of the male parent, the cultivar Isabella. In side-by-side comparisons conducted by the Inventor in De Lier, The Netherlands, plants of the new Kalanchoe differ from plants of the cultivar Isabella in the following characteristics:

1. Plants of the new Kalanchoe are more compact than plants of the cultivar Isabella.

2. Plants of the new Kalanchoe are more freely branching than plants of the cultivar Isabella.

3. Leaves of the new Kalanchoe are not as twisting as leaves of the cultivar Isabella.

4. Flower color of plants of the new Kalanchoe is darker and more intense purple than flower color of plants of the cultivar Isabella.

Plants of the new Kalanchoe can also be compared to plants of the cultivar Timor, not patented. In side-by-side comparisons conducted by the Inventor in De Lier, The Netherlands, plants of the new Kalanchoe differ from plants of the cultivar Timor in the following characteristics:

1. Plants of the new Kalanchoe are more freely branching than plants of the cultivar Timor.

2. Inflorescence form of plants of the new Kalanchoe is not as open as inflorescence form of plants of the cultivar Timor.

3. Plants of the new Kalanchoe flower earlier than plants of the cultivar Timor.

4. Flower color of plants of the new Kalanchoe is darker and more intense purple than flower color of plants of the cultivar Timor.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Kalanchoe, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kalanchoe. The photograph comprises a side perspective view of a typical potted plant of ‘Lican’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Unpinched plants used for the photograph and for the description were grown during the autumn in De Lier, The Netherlands, in a glass-covered greenhouse. During the production of the plants, the following measurements were recorded: day temperatures about 19 to 26° C.; night temperatures about 20 to 21° C.; and light levels about 10,000 to 50,000 lux. Unrooted cuttings were directly stuck in 10-cm containers and received long day/short night conditions (more than 14 hours of light) for about 22 days; plants then received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were about 14 weeks old from an unrooted cutting when the photograph and the description were taken.

Botanical classification: Kalanchoe blossfeldiana cultivar Lican.

Parentage:

Female or seed parent.— Kalanchoe blossfeldiana cultivar Iztac, disclosed in U.S. Plant Pat. No. 10,455.

Male, or pollen, parent.— Kalanchoe blossfeldiana cultivar Isabella, disclosed in U.S. Plant Pat. No. 9,427.

Propagation:

Type cutting.—Teminal cuttings.

Time to initiate roots.—Summer: About 10 days at 21° C. Winter: About 14 days at 21° C.
